GNU XaoS

fast interactive fractal zoomer

Dynamic resolution

Syntax:(fastmode keyword)

XaoS performs many optimizations, but fairly often this is not enough. In order
to keep a high framerate, XaoS automatically lowers the resolution of the image,
increasing it when there is time for more calculation. This feature is enabled by
default when animating, but you might also like to enable it for new images
(which makes the image `come into focus' when it is recalculated from scratch for
whatever reason), or disable it completely if you don't like it.
